|Strip cutting alfalfa helps control lygus in nearby cotton fields.|
- Maintain nearby alfalfa fields in a succulent condition.
- Avoid cutting all alfalfa fields in an area within a short time period. Leave an uncut strip or check at each cutting along the border between alfalfa and cotton to slow lygus migration.
- If lygus populations get very high, uncut strips of alfalfa may be treated with an insecticide if needed, but sprays should be avoided where possible to protect beneficials.
- Planting a sufficient area with alfalfa, manage for succulent growth, and alternate cutting half of each strip every two weeks.
- Cutting back with a stalk cutter. In a 28-day cycle, many lygus eggs will be inside the cut stems and will die as the stems desiccate.
